Metformin is very helpful for PCOS; it improves insulin sensitivity and helps restore regular ovulation, which actually supports conception. Regestrone (norethisterone), however, is a hormone used to regulate your periods. While actively taking Regestrone, your body's hormone levels and uterine lining are altered, making conception highly unlikely during those specific days. Once you stop Regestrone, your cycle resets. If you are planning to conceive soon, please discuss this with your gynecologist so they can safely adjust your treatment plan.

Since you have already had a negative pregnancy test, that is a reassuring start. Generally, doctors suggest waiting at least 7 to 10 days after a missed period before starting Regestrone (norethisterone) to induce your cycle. However, because hormonal medications should only be taken under professional guidance, it is very important to consult your doctor first. They will prescribe the correct dosage and duration. After completing the course, your period typically begins within 2 to 10 days.

Regestrone (norethisterone) can safely delay your period, but using it with recent irregular bleeding requires care. Since your cycle is already fluctuating, norethisterone might cause some spotting, bloating, or mild headaches. It is generally safe for short-term use, but delaying your period for an extended duration is not typically recommended without a doctor's supervision, as it can further disrupt your natural cycle. After stopping the medication, your period should return within 3 to 7 days. I gently recommend speaking with your doctor to rule out any underlying causes for your irregular bleeding before starting.

To delay your period, the standard recommended dose of norethisterone (Regestrone) is one 5 mg tablet taken three times a day. You should start taking it about three days before your expected period is due to begin. Continue taking it for as long as you need to delay your cycle (usually up to 10 to 14 days), and your period should arrive within 2 to 3 days after you stop taking it. Please consult your doctor before starting to ensure this is safe for you.

After finishing a 21-day course of Regestrone (norethisterone) on December 14th, a withdrawal bleed typically starts within 3 to 10 days. Sometimes, your body just needs a little extra time to reset its hormone levels, or mild stress can cause a delay. If you are sexually active, taking a home pregnancy test is a safe first step. If your period still hasn't arrived after 10 to 14 days from stopping the medicine, please consult your gynecologist. They can gently evaluate your hormone levels to ensure everything is on track.

Regestrone (norethisterone) is used to delay your period, but it is not a reliable contraceptive. Because you had unprotected sex, there is a risk of pregnancy. Your period should typically start within 3 to 7 days after you stop taking the medication. If your period does not arrive within a week of stopping it, or if you feel anxious, I gently recommend taking a home pregnancy test or speaking with your doctor for guidance and peace of mind.
